Bosch Dishwasher Error Code E14 — How to Fix (Flow sensor error)

If you’re seeing the E14 error code on your Bosch dishwasher, it can be frustrating and worrisome. This error indicates a flow sensor issue, which prevents the dishwasher from detecting water flow and completing the wash cycle. Don’t worry; we’ll walk you through what this error means, how to diagnose it, and steps to fix it.

What Bosch Dishwasher Error E14 Actually Means

The E14 error code on your Bosch dishwasher is related to the flow sensor. The flow sensor is responsible for measuring the water flow into the dishwasher. When the dishwasher detects a problem with the water flow, it displays the E14 error code. This error can occur due to a faulty flow sensor, clogged water inlet valve, or issues with the water supply.

The flow sensor is usually located near the water inlet valve and is responsible for monitoring the water flow into the dishwasher. If the sensor detects a problem, it sends a signal to the control board, which displays the E14 error code.

Is it safe to keep using the appliance? No, it’s not recommended to continue using the dishwasher with the E14 error code. The dishwasher may not be able to complete the wash cycle, and continued use can lead to poor cleaning performance, increased energy consumption, and potentially cause further damage to the appliance.

Quick Diagnostic Checklist (use before calling anyone)

Before calling a professional or spending money on repairs, try these quick diagnostic checks:

• Check the water supply: Ensure the water supply lines are not kinked, clogged, or restricted.
• Check the water inlet filter: Locate the water inlet filter and clean or replace it if necessary.
• Power cycle the dishwasher: Unplug the dishwasher from the power outlet, wait for 30 seconds, and plug it back in. This can sometimes reset the error code.

For Bosch dishwashers, the power cycle procedure is as follows:

1. Unplug the dishwasher from the power outlet.
2. Wait for 30 seconds to allow any residual power to dissipate.
3. Plug the dishwasher back in and turn it on.
